Having memory issues with my Mobo.


Recommended Posts

I'm having some memory issues, and I believe the root of the problem is the DFI NF4 SLI-DR. I'm not sure though, and I'm seriously hoping some of you will have some insights for me.

 

I got the components in my sig half a week ago and assembled the comptuer with no problem (Lian-Li cases are very nice, btw). I updated the BIOS to 6/23/2005 with no serious problems, and it recognized my AMD X2 4600+

 

All was going well during the Windows installation, until I had to reboot. Upon reboot I got the BSOD, citing a physical memory dump. I got a little worried and tried to re-install windows (after attempting to boot into safe mode to no avail) hoping it was just a wonky driver or something.

 

(By the way at this point I am using the memory in DIMM 2 and 4 Dual Channel. It detected the memory at DDR 400 Dual-Channel 128 bit. With the correct timings)

 

It happened again, and I started reading things on www.dfi-street.com hoping to find some answers. After a while I determined that my problem was indeed likely memory. So I ran MemTest, and for several runs I got no errors. So I upped the voltage from 2.6V to 3.0V just to see what would happen (someone mentioned something like that might help on these boards.) And lo and behold it booted to Windows.

 

Unfortunitally, it only booted to windows once, as on the second boot, I again encountered the BSOD. So after some fiddling, I eventually attempted, just for kicks, lowering the speed on the RAM. So I lowered my RAM from auto-detect in the Genie BIOS to DDR 200 and it started working fine. Now I, of course, didn't want to be stuck at DDR200, especially since I love playing video games, and that just hurts.

 

With my roomate we played with the location of the RAM, we put it into Single Channel config and set everything to auto and the voltage to 2.6 and it booted. Likewise, each stick of RAM by itself at 2.6V and auto-detect speed booted as well. So we tried DIMM slots 1 and 3 (which is where they are currently) and tried DDR400 again. But we got the BSOD. At this point I lowered it slowly, and found that if I put it at DDR366 (I believe thats the number?) it worked.

 

It was stable for 2ish days at this point, and I was ready to accept DDR366 in a Dual Channel Configuration (I ran PRIME95 for 8 hours, 6 hours, and a 1.5 hour session and it passed completely.)

 

Now this morning windows started acting funny (Text dissapearing on boot, some programs not running very well (read loading slow). After another reboot to regain my text I got the BSOD again. Then I nearly cried. So I turned down my RAM to DDR 333, and now it seems to be stable. But then again, it was stable before.

 

Does anyone know anything I can try to keep my system stable and get the best preformance without (hopefully) sacrificing the life of my RAM by upping the Volts to ungodly levels?

 

At this point I'm wondering if I should just try another Mobo, but I would definitely prefer not to because other than this one (albeit large) issue, I really like the DFI NF4 SLI-DR motherboard.

 

Thanks for any help,

Kevek

 

(P.S. If I'm missing any information in my sig/description I will be more than glad to provide it if you inform me... and thanks again.)

The surest way to know is to swap your current ram for some other sticks which are known to be good for certain. If your buddy can lend you his sticks for 30 minutes you can know for sure. PC3200 is pretty common these days and there are litterally millions of PCs that have been up and running well for a year or more with such ram. Borrowing a pair of road-tested sticks will do you a lot good.

 

If the roadtest sticks fail, you have a bad mobo.

If the roadtest sticks succeed in booting to Windows, you have bad ram.

 

Before testing, I would reinstall Windows with the known good sticks to make sure you have a good system image. Nothing can screw up an OS install like a pair of marginal sticks.

If it is a bad mobo, I have two additional questions:

 

1) What does DFI do? Do I take it up with newegg.com or DFI themselves to get a replacement

 

2) Since I used the stock heatsink/fan with the AMD CPU and it came with thermal paste on it (which I've never used before) How do I remove the Heatsink/Fan from the CPU without damaging it now that the paste has adhered?

 

Thanks again

David,

 

I attempted your suggestion first (It was easier, a friend ran to my room with 2x512 Corsair sticks) and they ran at the default "optimized" settings (that my OCZ sticks would not run at...)

 

So here's my question: Is this possibly due at all to the fact that his are 512MB sticks and mine are 1GB sticks? Or is it simply that my RAM is not very compatable with my board?

 

Thanks again for any help.

 

 

 

Edit: Angry_Games I tried all of your settings, and while on the first attempt I was able to boot into windows, it refused to load the audio-drivers, ethernet drivers, and it tooks 25ish minutes to get to the desktop (from power-on)

 

The second time I tried to boot with your settings I got the BSOD again... Any other ideas? =

 

Thanks again again...

this is incorrect for the most part on our overclocking Lanparty boards...there is no other motherboard with this kind of DRAM configuration available, and we get the common complaint that "this memory work(ed)/(s) fine on my (Asus/Giga/Epox/Abit/MSI/etc) motherboard but it wont work on the DFI NF4".

 

with these Lanparty boards, they do not run AUTO anything very well....especially memory...they are designed for tweaking and overclocking. They will run stock speeds no problem, but they still must be tweaked and most of the important DRAM settings must be set manually, not left on Auto.

 

and even then, some memory, most notably Corsair's modules, still do not work very well at all.

 

other memory that users here have tried and tested true, will work with some good config settings applied.

I would make sure you try memtest and some prime95 on each memory module separately first to make sure there is no problem with each individual memory stick.

 

i would also try to possibly test with a psu other than that Antec...in tech support email and these forums we've simply seen too many Antec psu problems on our boards.

Wow... another person with the same problem I have... So I'm really not insane thinking I'm the only one to have this problem...bytheway what are the errors you get in the BSOD, mine very to about 5 different ones depending on what slots I run the memory in, down to what timeings etc...

 

I'll let you know if I get mine solved and what I did to do so, I'm about to the breaking point also of trying a new MB, but now seeing that we have considerably about the same problem I'm very intrigued...

I like the DFI board, but I am nearly convinced that it is either too advanced for me, or just not compatable with a wide array of things on the market. Since no advice here has helped, I'm sorry to say that I'm leaning toward buying a new motherboard to replace this one... =
